如何采集防采集的网站
我想用php采集一个网站的数据,但是无法获取该网站的数据。网址如下:
http://www.alldatasheet.com/view.jsp?Searchword=78HC
希望您能试一下,只要能返回数据就行了。我试了很久不能成功。
[解决办法]
$header = array (

$curl = curl_init();
// 设置你需要抓取的URL
curl_setopt($curl, CURLOPT_URL, 'http://www.alldatasheet.com/view.jsp?Searchword=78HC');
curl_setopt($curl, CURLOPT_HTTPHEADER, $header); //设置header
// 设置header显示方式
curl_setopt($curl, CURLOPT_HEADER, 0);
// 设置cURL 参数,要求结果保存到字符串中还是输出到屏幕上。
